Fry the minced meat with butter and onions until crispy. Season with cayenne pepper.
In the meantime, cook the rice in 500 ml salted water until soft.
Then add the sliced carrots to the minced meat and fry. Add some water if it gets too sticky. Shouldn`t burn, but cook. If the carrots are the way you like them (with a bite or through), add the halved and sliced leek and cook it.
Fold the finished rice into the minced meat and vegetable mixture. Season with soy sauce. Finally fold in the diced paprika and just let it get hot.
Mung bean sprouts or other vegetables of your choice also taste good.
